-Referr-ngfirst tol ig ur sea-ts andB com-- prise a pair of individualside-by-sides'eats, and iikewise seat-s G and D compri'se an' individual.pair of side-by-side seats which are' used in" the uma/1 ina/imer by"the passengers for:` daytim'e travel. In 'order to afford a 'greatei'degree of cemfort tothe passengers ina teach-or' the'lke, -l prepose to'dispose-ah of the seats-in' horizontal 'planes and elevate 'every other.one in sta'ggerd relation for* exampieseat A Would be horizontalydisposedand -elevated andi seat B* would be horizontally disposed andallowed to remain at its original seat level. The seats in front of theseats A and B, namely, the seats C and D respectively, are disposedhorizontally and the seat C would remain at its normal seat level whilethe seat D would be elevated. It will be noted that a portion of theseat D overhangs a portion of the seat B when the seats are arranged inthis manner. Therefore, by elevating every other one in staggeredrelation, the seats need not be spaced further apart than standardspacing now employed in existing coaches or the like. Therefore thecoaches now in use may be equipped with new and improved convertibleseats as well as later models of coaches.

Each seat is provided with mechanism for automatically lowering the backthereof and swinging the footpiece in line with the seat. This automaticmechanism utilizes compressed air which is usually available in allcoaohes or the like.

Simultaneously with the movement of the back and footpieces asaforesaid;every alternate chair is raised to bring its plane ona higherlevel than that of its neighbor. All seats may preferably be constructedof aluminum alloy or similar light we ght material in order to keep allparts at a minimum of weight with"aconservative factor of safety. and atthe same 'time to efiect ec onomical use of the compressed air. i

The seats whichare raised are to be heightened to about four andone-half to five feet above the floor of the coach, thereb-y'improvingthe stability of the structure 'and at the same time giving thepassengers a feeling: of security, and the' passenszers may easily getinto them'. This also has anadvantage in that the center of gravity ofthe car is kept low. In order toffu'rther facilitate matters.short'lieht ladders maybe provided for the passengers to get into theelevated seats. These ladders may nest into each other and be kent in asmall closet or compartmentat the end of the car when not in use. g

The seats such as B and C, due'to thefact that they are not raised fromtheir normal leveleare su ported bv plain columns` which may be in theform of tubes, at least some one of which may lead air to the mechanismfor flattening out the seat. and another of which may 'lead air forreleasing the look ng mechanism holding the seat part-s at a horizontallane and motivating them .to their normal positions.

On the other hand, the columns supporting seats such as A and Dareexpansibly-collapsible so that the seatthereon may be raised to a higher'level and then fiattened out. In the v reverse order. the seat may belowered and restored to its normal position. Each seat of the tyne A orDis supported on four expansible-collapsible'.columns, each sectionbeing extendible'by compressed air to a pre-determined position andlocked'.

A fth column also eXpansible-collapsible is associated with each seatand serves to deliver air to the tops of the other four columns forrestoring the seat to its normal position as will hereinafter bedescribed.

Referring to Figure 2, the expansble-collapsible columns su porting theseat I) are generally designated by the numeral 20, and thefifth columnis generally designated by the numeral 2 l.

The details of the expansible-collapsible columns are shown in Figure 3.Referring to that figure, it will be noted that the outer or lowermostsection carries on its lower end 'in secured to the sub-floor 24 influid-tight relation by any suitable means such, for example, as thescrews 25, a suitable gasket or other scaling means (not shown) beingpositioned between the anged ring 23 and the floor. The section 22passes upwardly through a hole in the floor 26, and a suitable flangering 21 embraces the section and is secured to the floor 26 by means ofscrews 28. The upper end of the section 22 is provided with holes to beengaged by the looking means;

these holes and the looking means will presently be described.

A second section 29 forms a working fit in the section 22. Within thebottom end of the section 29 is mounted in sealed relation thereto, anannula' member 30 having its lower end provided with a counter-boredportion 3I. The member 30 als-o carriesbosses 32 and 33, and holesextend through these bosses and through the walls of the section 2 9 andform working fits for looking plungers 34 and 35, respectively. Normallythe plungers 34 and 35rest against the interior wallof the section 22and are urged outwardly by spring means 36 so that when the section 29moves upwardly, as will pre'sently be described, to a'point where theplungers encounter matching holes in the wall of the section 22, theplungers enter said holes, as will presently be described, and lock thesections in extended order( e V A metallc disc 31 is reciprocallymounted in 'the counter-bored portion 3| and carries' on its 'uppersurface boss es 38 and' 39.

A metallic disc 40 forms a working fit within the bore of the section 29and moves as a pisten therein along a path, theupper limit of which isdefined by an annular stop 4l. The pisten 40 carries on its lowersurface bosses 42 and 43.

The plunger 34 has a shank portion 44 which carries a stud 45; andsuitable pivot pins 46 and 41 ar'e mounted respectively in the bosses 38and 42. A link member 48 has one end pivotally connected to thepin 41,and the other end pivotally connected to the stud 45. Likewise, a link40 has one end pivotally connectd'to the pin 46, and the other endpivotally connected to the stud 45. Similar pivot pins and link membersare -asso'ciated with the bosses 39 and 43 and a stud carried bythe'plunger 35; but since this arrange- -ment is' 'id'entica'l' with thearrangement just described it'need not be here described in detail.

. However, the corresponding link members respecsealed relation theretoa fianged rin-g 23 which is 75 tively are designated by the numera`1s'59and 5I. "The piston 40has a central hole forined therein: This holeis'designated by the numeral 52 'and is stepped to form a valve seattherein, a suitable ball valve 53 seating therein is urgd toward theseat by means of a spring 54 which is retained inposition-by a retainer55.

Pivotallymou'nted in the boss 43 is a flapper valve 56 which co'vers thelower end of the hole 52 and is maintained in seated relation thereon bymeans of a spring. When pressure enters the lower end of the section 29,this pressure also tends to keep the valve 55 closed until the sectionmoves up to the point where the plungers 34 and 35 encounter holes inthe outer section 22 and move outwardly. When this occurs, a stud 58carried on the link member engages a crank 'arm' 59 secured to the valveand thereby swings the valve 56 downwardly off its seat This per- -mitsthe compressed air to pass into the opening 52 and 'to thereby raisethe'ball valve 53 off of its seat, whereupon said air may pass into thethird section 60.' The lower end of'the third section is provided withthe same kind of pistons,

The other end of thelink IGS'has a. cross hole therein journaled on'the stud shaft !9 whichis supported on the seat bottom' 9! by means 'of bearings'! !2 and !!3..A second link !lLhas one endjournaled on a istub' shaft ^!'!4,=supported by bearings !5 and !!6 on the ifoot-piece ln; and the otherend journaled on a, stub shalt! !'!,"supported by bearings !!8 and!IS-on the seat bot `tom 9!. The links !06 and' l form hinge connectionsbetween the bottom and the foot-piece.

A U-shaped bracket !29,- carried on the lower end of !the back 92,carries a stub shaft !2! upon which one end c f-8, bar !22 is journaled.The

other end of the bar !22 ispivotally' connected to the midpoint of thelink !05 by means'of a- A hook -shaped member !28 is"mounted on' thebottom end of the back 92 and has a portion !29 thereo-f forming a camsurface. A second hockshaped member supported on a' piston rod extension!4! mounted in a. cylinder !3!, is carried within the bottom 9! of theseat. I The member !30 -is also provided'with a cam surface !32. Now,eis to the operation for fiattening the seat, bringing the back 92 andthe bottom e! and the foot-piece into alignment with each other along ahorizontal plane, air from the manifold 69 passes'from the nipple 15via. the flexible connector (not shown) and the nipple l into thecylinder 'la and acts upon the pisten 84 and movesthe'same toward theleftjas viewed This tends to increase' the 'distance between the stubvshaft 8! and thestub shaft 88, and thereby causes the back 92 to movedown; wardly toward the horizontal plane.

Now due to the linkages between thebars !22 and !26 and the linkmembersl'fl and I i, respectively, the foct-piecelll is at the same timeraised toward the horizontal plane. Asthe piston 84 continues to move"to the leftgas viewed in Figur' i, the "hook-shaped member !28 andthehcok-shaped member !337 engage *each other. 'First the 'cammingsurfaces !29 and !32 contact each `other and further motion fiectsr theen-- gagement of the hock-shaped'portionsef 'me members !23 and !39 witheaeh other; thereby looking the seat back' 92 and the foo't-piecelfl inalignrnent` with the seat bottom 9l; making the seat into a device uponwhich thevlpassenger may recline. i i

The positions of the parts, when the seat is horizo-ntally disposedasjust described, 'may be seen in Figures 6, 7, and 8.

In addition to the looking efiect ofthe hookshaped members !28'and ISS;bolts !33 and !34, slidably mounted in blocks !35 and !36 respectively,are provided for engaging the' bars !22 and !25. This looking effect maybe seen in Figure 8, wherein the bolt !33 snaps out beneath the bar !22,making it impossible for the bar !22 to `!neve downwardly until released(see Figures &and 8). i

The bolt !33 is pivotally connected to a link !31, which is in turnpivotally connected to a bell crank !38. .The'bell crank !3315 pivotally!43 carried by the ben crank s'a operates. A second bell crank !44pivoted to the Irame at !45 carries a stud !46 which also engages'theslot !42. The other 'arm of the bell crank is "linked to thebolt 34 bymeans of the link member !47. 1

The cylinder I'J! carries a piston, !48 'which is connected to both thepisten rod !4!' and the i .pisten rod extension !4! The end of the cylinder is capped wlth a suitable stufllng box !48, and 'a spring !50 withinthe cylinder !3! tends to urge the pisten toward the right end, asviewed in Figure 4'. A nipple 15! communicates with the interiorcf thecylinder'and is flexibly connected (not shown) to a nipple !52communicat- 'ing with the manifold !53, so that when air is supplied tothe manifold !53, as will presently 'be described, air may enterthecylinder !3! Via the nipple !51 and act against the pisten !48,moving it to the left, as Viewed in Figure 4, and

-thereby withdrawing the bolts !33 and !34 from b'eneath the bars 22 and!26 and at the same time dsengaging the hook-shaped member !39 from thebook-shaped member !33.

At the same time air from the manifold !53 passing via the nipple !55 onthe cylinder l:) acts 'against the 'pisten 84 and moves it to theright', as viewed in Figure 4, thereby shortening the distance between'the shafts 8! 'and 83 and causing the back 92 to'sWing upwardlyt and'thefoot-piece !95 to Swing downwardly, and bring the seat to its' normal.upright position. This action is abetted by the springs 99 and !30. Itmust be remembered at the same time this occurs, some of the air causesthe extended columns supporting the seat 'to collapse'and bring the seatdown to its normal sitting level.

Referring now to ,Figures 2 and 9,. the filth column, designated by the'numeral 2!, consists of 'a series of extensible pipes which areconnected to a source of air when it is desired to restore the seat toits normal level and position.

A ball valve is seated in the valve body by means of a spring s, andthis valve prevents air ;from the maniiold 69 from entering the manifold!53 and permits air from 'the manifold !53 to enter the manifold 59.Other valves !59 !a oand !59 which are identicel with the valve !59, areincluded in circuits between the manifold !53 and the maniold &9. Itmust remembered that air after it -has extended the coiumns may enterthe manifold .59 and thence passinto the cylnder '!8 Viathe nipple' ''lfor bringing the parts of the seatinto ashorzontal plane. This air isprevented ironi entering the inanifold !53 by the series of Valves !59to !59 inclusive. i

The air for restoring the seat. to its normal level and upright positionis all supplied to the manifold !53 via the fifth column 2l. Part of theair passes via the nipple !52 to the cylinder 13 via the nipple !5I andpart of it passes ,to the ;able end extensions *!-32, and the backs maybe provided with similar extensions !3:3 to further insure thepassenger@ comfort. r
